Function template: swap values

 


#include <iostream>
using namespace std;

template <class X> void swapargs(X &a, X &b)
{
  X temp;

  temp = a;
  a = b;
  b = temp;
}

int main()
{
  int i=10, j=20;
  float x=10.1, y=23.3;

  cout << "Original i, j: " << i << ' ' << j << endl;
  cout << "Original x, y: " << x << ' ' << y << endl;

  swapargs(i, j); // swap integers
  swapargs(x, y); // swap floats

  cout << "Swapped i, j: " << i << ' ' << j << endl;
  cout << "Swapped x, y: " << x << ' ' << y << endl;

  return 0;
}
